What Kind of Provision Should Be Made in a Will for a Blended Family?
8 minute read
When relationships overlap, clear planning helps prevent future misunderstandings.
Blended families are increasingly common and come in many forms. You might be in a new relationship after a divorce or bereavement, with children from that earlier relationship. Your new partner may have children of their own. You may have had children together as well. The combinations are as varied as the families themselves.
What they share, however, is a set of legal and practical challenges that a standard Will, let alone no Will at all, is often poorly equipped to handle. When there are children from different relationships, competing loyalties, and complex emotional dynamics in play, the decisions you make in your Will carry real consequences for the people you love most.
This guide addresses the key issues a Will for a blended family needs to address, and explains why taking professional advice before drafting is so important in these circumstances.

Why the Intestacy Rules Fail Blended Families
The intestacy rules are the legal framework that determines how an estate is distributed when somebody dies without a valid will. They follow a fixed order of priority: spouses and civil partners, then children, then more distant relatives. They were designed with the traditional family unit in mind, and they work reasonably well in straightforward cases. But in a blended family, they are almost guaranteed to produce an outcome that does not reflect your actual wishes.
Consider a typical scenario. A man has two children from his first marriage. He remarries, and his new wife has a child from her previous relationship. Together, they also have one child of their own. He dies without a will.
Under the intestacy rules, his estate passes first to his surviving spouse. His biological children from the first marriage receive nothing unless the estate exceeds a threshold known as the statutory legacy, currently set at £322,000. His stepchild, his wife’s child from her previous relationship, receives nothing at all, regardless of how close their relationship was, because stepchildren have no automatic right to inherit under the intestacy rules. Even his biological child from the second marriage may receive far less than he would have intended if the bulk of the estate passes to the surviving spouse.
And there is a further complication. Once the surviving spouse inherits the estate, she is free to do whatever she wishes with it. She might remarry. She might change her mind about who she wants to benefit. She might, entirely understandably, prioritise her own children over her late husband’s children from his first marriage. There is no legal mechanism under the intestacy rules to prevent any of this.
The intestacy rules do not recognise the nuance and complexity of blended family life. A will does, but only if it is carefully and thoughtfully drafted.
The intestacy rules were not written with blended families in mind. Without a will, your estate may not reach the people you intended. We can help you change that.
Why This Matters Even More for Unmarried Couples
If you and your partner are not married or in a civil partnership, the consequences of dying without a will are even more severe. Under the intestacy rules, an unmarried partner has no automatic right to inherit anything from your estate, regardless of how long you have lived together, how financially intertwined your lives are, or how clearly your intentions were expressed during your lifetime.
This is a point that cannot be overstated, as the myth of common-law marriage is still widely believed. There is no such thing in England and Wales. Cohabiting partners, no matter how long-established the relationship, are legal strangers to one another for the purposes of inheritance.
In a blended family context, this creates compounding difficulties. If you die without a will, your partner may receive nothing. Your estate may pass to your children, including children from a previous relationship who are now adults with their own lives. The family home might need to be sold to facilitate that distribution. Your partner and any young children you have together could be left in an extremely vulnerable financial position.
Even if your partner chose to make a claim against your estate under the Inheritance (Provision for Family and Dependants) Act 1975 as a cohabiting partner, such claims are uncertain, stressful, and costly. They are not a substitute for a properly made will.
If you are in a blended family and not married, making a will is not merely advisable. It is essential.
Stepchildren and Inheritance: Understanding the Legal Position
One of the most common misconceptions among blended families is that a stepchild will be treated in the same way as a biological child for the purposes of inheritance. They will not, unless you make specific provision for them in a will.
Under the intestacy rules, the term “children” refers to biological children and legally adopted children only. A stepchild, however close the relationship and however much they have been treated as your own, has no automatic right to inherit from your estate if you die without a will. They are not recognised as a child of the deceased for these purposes.
This means that if you want your stepchildren to benefit from your estate, you must say so explicitly in your will. You need to name them, or describe them in a way that clearly includes them, and specify what you want them to receive. A general gift to “my children” in a will is also likely to be interpreted as referring only to your biological or adopted children, not your stepchildren, unless the will makes the broader intention clear.
If you have stepchildren who are financially dependent on you, or who you regard as your own in every practical sense, your will is the only legal instrument that can give effect to that relationship. Taking the time to address this properly, with professional guidance, is one of the most important things you can do for them.
Providing for Children from All Relationships
A central challenge in drafting a will for a blended family is making fair and workable provisions for children from all relationships: your children from a previous relationship, your partner’s children from their relationship, and any children you have together. Each group may have different needs, ages, and relationships with the surviving partner, and those differences need to be reflected in how the will is structured.
Children from a Previous Relationship
If you have children from a previous relationship, there is a real risk that their interests could be unintentionally sidelined if your estate passes entirely and unconditionally to your surviving partner. Even where your partner has the best of intentions, life can change. They may remarry, and a new spouse could acquire rights over the estate. They may change their will. They may face financial pressures that deplete what remains.
One way to address this is through a life-interest trust, also called an interest-in-possession trust. Under this arrangement, your surviving partner is given the right to live in the family home and to receive income from the estate during their lifetime, but the underlying capital is preserved for your children from the previous relationship on the death of the survivor. This gives your partner the security they need while ensuring that your children are not forgotten.
Another approach is to leave specific assets or a defined share of your estate directly to your children from the previous relationship at the point of your death, rather than waiting until the survivor also dies. This is more straightforward but reduces what is immediately available to the surviving partner, so it requires careful thought about the relative financial needs of each group.
Children of the Current Relationship
Children from your current relationship are in a somewhat different position, particularly if they are young. If both parents die, they will need not only financial provision, but also a guardian to care for them on a day-to-day basis. They may also need their inheritance to be held and managed for them until they are old enough to benefit from it directly.
A well-drafted Will can address all of these points. It can create a trust to hold any inheritance on behalf of young children until they reach a specified age, appoint trustees to manage that trust responsibly, and specify how the money can be used in the meantime for the children’s maintenance, education, and welfare.
Appointing a Guardian: A Critical Decision for All Parents
If you have children under the age of eighteen, your will is the appropriate place to appoint a guardian to care for them if both parents die. For many parents, this is the single most important provision in the entire will, and it deserves careful and considered thought.
Guardians for Children from a Previous Relationship
Where children have two living biological parents, the surviving parent will normally assume full parental responsibility on the death of one parent, regardless of what any will says. A guardian named in your will would only step in if the other biological parent is also deceased, or in exceptional circumstances where they are unable to care for the children.
However, if there is no surviving biological parent, or if the circumstances of the other parent give you cause for concern, naming a guardian in your will is the only way to put on record who you would want to care for your children. Without that appointment, the court will decide, and it may not reach the same conclusion you would have.
Guardians for Children of the Current Relationship
Where children have been born into or adopted by the current blended family, the guardian appointment needs to reflect the full picture of the family. If both partners die simultaneously, which partner’s family or network of friends should step in? Should the guardian be the same person for all of the children in the household, or would it be more appropriate to appoint different guardians for children from different relationships?
These are genuinely difficult questions, and there is no universally right answer. What matters is that you think them through carefully, discuss them with the people you are considering, and record your wishes formally in your will. Speaking to a professional Will drafter about these decisions is particularly valuable because they can ask the questions that help you think clearly about a scenario most people prefer not to imagine.

Provision for Vulnerable or Disabled Beneficiaries
In some blended families, one or more of the children or other beneficiaries may have a disability, a mental health condition, or other vulnerability that affects how they should receive any inheritance. For these beneficiaries, an outright gift under a will may not be the right solution.
A large inheritance received directly can affect eligibility for means-tested state benefits, potentially reducing the financial support the person relies on for their care. It can also expose a vulnerable person to financial exploitation or simply place them in the difficult position of managing a sum of money they are not equipped to handle independently.
A discretionary trust written into your will can address these concerns. Rather than leaving assets directly to the beneficiary, you leave them to a group of trustees with the power to apply the assets for the beneficiary’s benefit at their discretion. Because the beneficiary does not legally own the trust assets, the trust should not automatically affect their entitlement to means-tested benefits, though specialist advice on the specific benefit rules is always recommended.
This kind of provision requires careful drafting, and it is one of the situations where professional will-drafting expertise makes the most material difference to the outcome.
When You Choose to Omit Someone: Managing the Risk of a Claim
In a blended family, it is not unusual for a will-maker to decide to make limited or no provision for a particular person, whether a child from a previous relationship with whom contact has been lost, a stepchild they do not feel a close connection to, or some other relative who might otherwise expect to benefit.
In most circumstances, the law in England and Wales allows you to leave your estate to whoever you choose. There is no automatic legal obligation to provide for any relative simply because of their relationship to you. However, there is an important exception.
The Risk of a Claim Under the 1975 Act
Under the Inheritance (Provision for Family and Dependants) Act 1975, certain categories of people are entitled to apply to the court for reasonable financial provision from your estate if they feel that your will, or the intestacy rules, has not made adequate provision for them. Those categories include your spouse or civil partner, your former spouse or civil partner in certain circumstances, a cohabiting partner, your children (including adult children), and any person who was financially dependent on you.
In a blended family, the range of people who might potentially bring a claim is therefore quite broad. An adult child from a first marriage who has been left nothing may have grounds to apply. A stepchild who was financially dependent on you for many years might also have a claim, even without a formal legal relationship.
It is important to understand that the existence of a potential claim does not mean a claim will succeed. The courts apply a careful balancing exercise, and the threshold for obtaining provision under the Act is not a low one. But a claim, even an unsuccessful one, is stressful, expensive, and damaging to family relationships. Prevention is always preferable.
How a Letter of Wishes Can Help
One of the most effective ways to reduce the risk of a successful claim, and to demonstrate that any omission or limited provision was deliberate and considered rather than accidental, is to accompany your will with a carefully drafted letter of wishes.
A letter of wishes is a separate document, addressed to your executors and potentially to the court, in which you explain in your own words the reasons behind your decisions. If you have chosen to leave a stepchild nothing because you have had no contact for many years, you can say so. If you have made limited provision for an adult child because they are financially independent and the needs of a younger child are greater, you can explain that reasoning.
A letter of wishes is not legally binding. It does not guarantee that a claim under the 1975 Act will fail. But it carries real evidential weight, and it significantly strengthens the position of your estate if a claim is ever made. It demonstrates that the will reflects a genuine and considered exercise of your testamentary wishes, not an oversight or an error.
The letter of wishes needs to be drafted with care. It should be consistent with the will, it should be specific rather than vague, and it should be honest. Your will drafter can help you to produce a letter that serves its purpose effectively.

The Importance of Getting Professional Help with a Blended Family Will
A blended family Will is not a job for a template or a DIY will kit. The decisions involved are too important, the legal issues too specific, and the potential for unintended consequences too significant.
The combination of competing interests, multiple categories of beneficiaries, potential trust structures, guardian appointments, and the risk of 1975 Act claims means that this is precisely the area of will drafting where professional expertise adds the most value. A will drafter who understands blended family dynamics can ask the right questions, identify the issues you might not have thought of, and produce a document that genuinely reflects your wishes and gives them the best possible chance of being carried out.
The cost of getting a blended family will professionally drafted is modest. The cost of getting it wrong, in terms of family conflict, legal disputes, and assets reaching the wrong people, can be considerable.

Frequently Asked Questions
Do stepchildren automatically inherit if I die without a will?
No. Under the intestacy rules in England and Wales, stepchildren have no automatic right to inherit. Only biological children and legally adopted children are recognised as children of the deceased for the purposes of intestacy. If you want your stepchildren to benefit from your estate, you must make a will and name them explicitly.
Can I leave everything to my current partner and rely on them to provide for all the children?
You can, but this approach carries real risks in a blended family. Once your partner inherits your estate outright, they are free to deal with it as they choose. They could remarry, change their will, or simply make different decisions about their own estate. Children from your previous relationship, in particular, may find themselves left with nothing. A life interest trust can provide for your partner while protecting the interests of all your children.
My partner and I are not married. What happens to my estate if I die without a will?
Your estate will not pass to your partner. Under the intestacy rules, an unmarried partner has no automatic right to inherit. Your estate will pass to your children, or to other relatives if you have no children. Making a will is the only way to ensure your partner is provided for.
Can I appoint a guardian for my children in my will?
Yes, and it is strongly recommended if you have children under eighteen. Your will is the appropriate place to record who you would want to care for your children if both parents were to die. In a blended family, guardian appointments require particularly careful consideration, given the various relationships involved.
What is a life interest trust, and why might it be useful in a blended family will?
A life interest trust allows you to provide for your surviving partner during their lifetime while ensuring that the underlying assets eventually pass to your chosen beneficiaries, such as your children from a previous relationship. Your partner has the right to live in the family home and to receive income from the Trust, but cannot spend the capital. This is one of the most commonly used tools for balancing competing interests in a blended family will.
Can a stepchild or former partner challenge my will?
Certain people, including children, cohabiting partners, and financially dependent individuals, may be entitled to bring a claim under the Inheritance (Provision for Family and Dependants) Act 1975 if they feel that reasonable financial provision has not been made for them. The risk of such a claim can be reduced by careful will drafting and by producing a well-reasoned letter of wishes explaining the decisions you have made.
