Will

A will is a legal document in which a person, known as the testator, sets out instructions for how they want their money, property and other assets distributed after their death. A valid will typically also allows the testator to name an executor, the person responsible for carrying out those instructions, and can address other matters such as the guardianship of minor children left behind.

Each jurisdiction sets specific legal formalities that a will must satisfy to be considered valid, commonly including requirements around the testator's mental capacity, proper signing, and witnessing by independent parties; a will that fails to meet these requirements may be declared invalid, with the estate then distributed according to the laws that apply when someone dies without a valid will in place. Once a person dies with a valid will, the document generally must go through a court process known as probate before the executor can formally distribute the estate to beneficiaries.

A will is simply your own written instructions for what should happen to everything you own once you are gone, and who should be in charge of making sure those instructions are actually carried out properly on your behalf.

A valid will lets a person choose exactly who receives their assets, rather than relying on default rules set by law that may not reflect their actual wishes, allows the testator to name their preferred executor and, where relevant, a guardian for minor children, and can reduce disputes and delays among family members after death by making the deceased person's wishes clear and legally documented.

Someone who dies without a valid will is said to have died intestate, and in that situation the estate is distributed according to a fixed legal formula set by the relevant jurisdiction, which may not match what the deceased would actually have wanted, and a court-appointed administrator, rather than a chosen executor, typically handles the estate instead.

Major life events such as marriage, divorce, the birth of a child, or a significant change in assets are generally recognized as prompts to review and, if necessary, update an existing will, since an outdated will may no longer reflect the testator's current family situation or wishes, and in some jurisdictions certain life events can automatically revoke an existing will entirely. Rather than drafting an entirely new will for every minor change, many legal systems allow a smaller amendment, called a codicil, to adjust specific provisions while leaving the rest of the original will intact.

A will generally governs assets held solely in the deceased's own name, but it typically does not control assets that pass automatically by other means, such as jointly held property that passes directly to a surviving co-owner, or a retirement account or insurance policy with its own separately nominated beneficiary. Keeping beneficiary nominations on these separate accounts up to date alongside the will itself is important, since a conflict between an outdated beneficiary nomination and the wishes expressed in a current will can create confusion or disputes during estate administration.

A will can be challenged in court by someone who believes it is invalid, perhaps because the testator lacked mental capacity at the time of signing, was subjected to undue influence or fraud, or because the document failed to meet the jurisdiction's required legal formalities for a valid will. Successfully contesting a will can be difficult, since courts generally start from a presumption that a properly signed and witnessed document reflects the testator's genuine wishes, placing the burden of proof on whoever is challenging it to show otherwise.

As more of a person's financial and personal life exists in digital form, including online banking access, cryptocurrency holdings and digital subscriptions, modern estate planning increasingly addresses how these digital assets should be identified, accessed and transferred after death, an area that older, more traditional will templates often overlooked entirely. Testators are increasingly advised to maintain a separate, securely stored list of digital accounts and access instructions alongside their will, since an executor who cannot even identify what digital assets exist has no realistic way to administer them as part of the estate.
