How to Write a Simple Will (and Why You Should)
To write a simple will, you put in writing who should receive your property, name an executor to carry out your wishes, appoint guardians for any minor children, and sign the document in front of witnesses. Most jurisdictions require the will to be written, signed by you, and witnessed by adults who are not beneficiaries — though the exact rules vary by country. A simple will suits straightforward situations; complex assets, blended families, or cross-border property usually call for a qualified legal consultant.
What does a will actually do?
A will is a written document that says what should happen to your property when you die. It lets you choose who inherits, who manages the process, and — if you have children under the age of majority — who you would want to raise them. Once you die, the person you named as executor uses the will to gather your assets, pay your debts, and distribute what remains to the people you chose.
A will only takes effect at death. It does not control jointly owned property that passes automatically to a co-owner, and in many countries it does not control life insurance or pension money that already has a named beneficiary. Knowing which assets a will covers — and which it does not — is one of the most useful things you can clarify before you start writing. This is a core part of family law and estate planning, and the rules differ from one jurisdiction to another.
What happens if you don't write a will?
If you die without a valid will, the law of your country decides who inherits, using fixed rules usually called intestacy or forced succession. Those rules follow bloodlines and marriage, not your actual relationships — an unmarried partner, a stepchild, or a close friend may receive nothing, no matter how long you were together. A court also chooses who administers your estate and, if you have minor children, who cares for them.
The result is often slower, more expensive, and less predictable than what a short document could have achieved. We cover this in detail in what happens if you die without a will — reading it first is a good motivator for finishing yours.
What does a basic will include?
Most simple wills contain the same handful of building blocks:
- Identification and revocation. Your full name and a statement that this document is your will and revokes any earlier wills. This prevents confusion if an old will surfaces later.
- An executor. The person (or professional) who will carry out the will — collecting assets, paying debts, and distributing the estate. Choose someone organised and trustworthy, and name a backup in case your first choice cannot act.
- Beneficiaries. The people or organisations who inherit. Identify them clearly — full names and their relationship to you — so there is no doubt about who you meant.
- Guardianship of minor children. Who you would want to raise your children if no other parent survives. In most places this is an expression of your wishes that a court will strongly consider, rather than an automatic appointment.
- Specific gifts. Particular items or sums going to particular people — a piece of jewellery to a niece, a fixed amount to a charity.
- The residuary estate. A clause covering everything else — whatever is left after debts, expenses, and specific gifts. This is often the most valuable part of the estate, and forgetting it is a classic drafting error: anything not covered may pass under intestacy rules instead of your will.
If terms like executor, residuary estate, or intestacy are new to you, our legal glossary explains them in plain language.
What makes a will legally valid?
Validity requirements differ by country, but most systems share a common core:
- It must be in writing. Typed or, in some jurisdictions, handwritten. Purely spoken wills are recognised only in narrow circumstances, if at all.
- You must have capacity. You generally need to be an adult and understand what you own, who might expect to inherit, and what the document does.
- You must sign it. Usually at the end of the document, intending it to be your will.
- Witnesses are usually required. Many jurisdictions require you to sign in the presence of witnesses — commonly adults who are present at the same time and who then sign themselves. A critical detail in many places: a beneficiary (or their spouse) who acts as a witness may lose their inheritance, even though the will itself remains valid.
Some countries add or substitute other formalities — notarisation, registration, or recognition of fully handwritten (holographic) wills without witnesses. Some also restrict how freely you can disinherit close family, through forced heirship or family provision rules. Because these details decide whether your will works at all, confirm the exact requirements for your country with a qualified legal consultant before you sign.
What are the most common mistakes people make?
- Invalid witnessing. Wrong number of witnesses, witnesses who did not actually watch the signing, or a beneficiary acting as a witness. This is the mistake most likely to sink a DIY will.
- Not updating after life changes. In many jurisdictions, marriage revokes an existing will unless it was made in contemplation of that marriage, and divorce often cancels gifts to a former spouse. New children, new property, and deaths of beneficiaries or executors also call for a review.
- Vague or contradictory wording. "My savings to my children" — which accounts, which children, in what shares? Ambiguity invites disputes and court applications.
- Forgetting the residuary clause. Leaving assets unmentioned means part of your estate may pass under intestacy rules despite your having a will.
- Amending by hand after signing. Crossing things out or writing in the margins of a signed will is usually ineffective. Changes normally require a formally executed amendment (often called a codicil) or a new will.
- Assuming the will covers everything. Joint accounts, insurance payouts, and pension nominations may pass outside the will entirely.
When is a simple will enough — and when should you get help?
A simple will generally works when your situation is straightforward: you are leaving everything to a spouse, partner, or children in clear shares, your assets are in one country, and no one is likely to challenge your wishes.
Consider professional help if any of the following apply:
- You own property or assets in more than one country — different succession laws may apply to different assets.
- You have a blended family — children from a previous relationship, a current partner, and competing expectations.
- You own a business or hold significant investments.
- You want to provide for a dependant with a disability or set conditions on an inheritance, which may require a trust or equivalent structure.
- You expect someone to challenge the will, or you plan to leave out a close family member — some jurisdictions limit your freedom to do this.
- Inheritance or estate tax planning matters in your country.
The cost of getting a will professionally checked is small compared with the cost of a dispute or a failed document.

How should you store and update your will?
A will only helps if it can be found — and if it still reflects your life. Keep the signed original safe: with a notary or lawyer, in an official wills registry where your country offers one, or in a secure place at home that your executor knows about. Do not staple, unstaple, or mark the original, as physical alterations can raise doubts about tampering. Tell your executor where the will is and give them a way to access it; a copy they can read is useful, but courts typically want the original.
Then review the will at regular intervals — many people use a rough rule of every few years — and after every major life event: marriage, divorce, a new child, a significant purchase or sale, a move to another country, or the death of an executor or beneficiary. A will is not a one-time task; it is a short document you keep aligned with your life.
