When a family includes children from previous relationships, a new spouse or partner, and a shared home, good intentions can pull in several directions. A blended family example makes the risk clear: without a properly written will, the people you most want to protect may not receive what you expected.
This is not about choosing one side of the family over another. It is about setting out fair, workable arrangements while you can still explain your wishes clearly. For many families, a simple will is enough. Where a home or significant assets are involved, a trust may offer added protection.
A blended family example: what could happen without a will
Imagine that David has two adult children, Ella and Tom, from his first marriage. He is now married to Priya, who has one teenage daughter, Leila. David and Priya own their home together and want the surviving spouse to remain there if one of them dies. They also want all three children to benefit eventually.
David assumes that, if he dies first, Priya will inherit everything and later divide it fairly between the children. But that is not a legal plan. It relies on circumstances, relationships and promises remaining unchanged for years.
If David dies without a will in England or Wales, the intestacy rules apply. Priya may receive a share of his estate, but David’s children may also become entitled to part of it, depending on the value of his estate and how the property is owned. Leila, as David’s stepdaughter, has no automatic right to inherit from him unless he legally adopted her or named her in a will.
Even where Priya receives the home or most of the estate, there is another concern. She could later need care, remarry, make a new will, face financial pressure or simply have different priorities. Ella and Tom could ultimately receive less than David intended, or nothing at all. This is not necessarily anyone behaving badly. It is what can happen when a family’s future is left to assumption.
What a clear will can do instead
David could make a will that leaves a specific cash gift or personal items to Ella and Tom, with the remainder passing to Priya. He could also make arrangements for Leila if he wishes to treat her as part of his family. A will gives him the opportunity to name every beneficiary rather than relying on legal definitions of spouse, child or next of kin.
However, leaving everything outright to Priya may not meet David’s longer-term aim of protecting his own children’s inheritance. This is where the details matter.
One option is for David and Priya to consider a Flexible Life Interest Trust or a Protective Property Trust. Broadly, these can allow the surviving partner to continue living in the home or benefit from it during their lifetime, while preserving the deceased person’s chosen share for the children later. The right solution depends on how the property is owned, the size of the estate, the couple’s finances and their priorities.
A trust is not automatically the best answer for every blended family. It can bring extra administration and should be set up carefully. But for homeowners who want to balance security for a surviving spouse with certainty for children from a previous relationship, it is often worth considering.
Start with the home, not the household budget
The family home is usually the most valuable asset and the one most likely to cause worry. Before deciding what to put in a will, establish how it is owned.
If a couple own a property as joint tenants, the deceased owner’s share normally passes automatically to the survivor. It does not pass under the will. This may be suitable for some couples, but it can make it harder to ring-fence a share for children from an earlier relationship.
If they own as tenants in common, each person owns a distinct share, which can be left by will. That can make a property trust possible. It does not mean the surviving partner must immediately move out. Properly drafted arrangements can provide a right to remain in the property while making clear where the deceased person’s share should go in the future.
The distinction is significant, so do not assume the wording on a mortgage or Land Registry document tells the whole story. Check the ownership position before making plans around the home.
Be precise about children and stepchildren
In ordinary conversation, a stepchild is family. Under inheritance rules, the position can be much narrower. A stepchild does not automatically inherit under the intestacy rules merely because they were raised by or close to the person who died.
A will lets you address that gap directly. You can name stepchildren as beneficiaries, leave them a fixed amount, give them an equal share with your own children or make a different arrangement that reflects your family life. Clear names and relationships are better than vague phrases such as “my children”, especially where there are children from more than one relationship.
Think, too, about what happens if a child dies before you. You may want that child’s share to pass to their own children, rather than being divided only among the surviving beneficiaries. Small decisions like this can prevent difficult questions at a painful time.
Do not rely on a promise to “sort it out later”
Many couples make informal agreements: the survivor will keep the house, then leave it to all the children in due course. The difficulty is that a promise does not bind the survivor’s future estate in the same way as a carefully considered will or trust arrangement.
Life changes. A surviving spouse may remarry, become unwell, need to sell the property, lose capacity or face pressure from other relatives. They may also make a perfectly valid new will that reflects their changed circumstances. Your original wishes could be overtaken without anyone intending harm.
Writing your wishes down is not a sign of mistrust. It is a practical way to protect the surviving partner from uncertainty and protect the children from feeling overlooked.
Choose executors who can handle family sensitivities
An executor deals with the practical work after death: valuing the estate, paying debts, applying for probate where needed and distributing what is left. In a blended family, this role can be particularly sensitive.
A surviving spouse may be the obvious choice, but it may help to appoint a second executor as well. This could be an adult child, another trusted relative or a professional, depending on the estate and relationships involved. The aim is not to create sides. It is to ensure someone can manage the estate fairly and communicate clearly with everyone affected.
Avoid appointing someone simply because they are the loudest person in the family. Choose people who are organised, trustworthy and capable of dealing with paperwork and difficult conversations.
Remember that marriage can change an existing will
A will made before marriage is usually revoked when you marry, unless it was made in contemplation of that particular marriage. This catches many people out, especially those who made a will after a first divorce or when their children were young.
If you have remarried or entered a civil partnership, check whether your current will remains valid and reflects your present family. Likewise, review it after buying a home, having a child, separating, receiving an inheritance or experiencing a major change in health or finances.
A separation does not automatically have the same effect as divorce. Until the legal position is finalised, an estranged spouse may still have rights under an existing will or the intestacy rules. If this applies to you, do not put off getting your will reviewed.
Make the will valid as well as fair
The best instructions are no use if the will is not signed properly. For a standard will in England and Wales, you must sign it in the presence of two witnesses, and the witnesses must also sign in your presence. Witnesses should be independent adults. A beneficiary, or the husband, wife or civil partner of a beneficiary, should not act as a witness because this can affect their gift.
Keep the original will somewhere safe and make sure your executors know where it is. A document stored in a drawer that nobody can find may cause almost as much delay as no will at all.
English Wills helps make the process more manageable with plain-English questions that prompt you to consider beneficiaries, executors and the arrangements that matter to your household. If your circumstances involve property trusts, a former partner, dependent children or possible disputes, take extra care over the options you choose.
The right blended-family arrangement is rarely about dividing everything into identical portions. It is about recognising who needs security now, who you want to benefit later, and putting those decisions in writing while you are able to do so.
