Can I write my own will in Finland?
Yes — a lawyer isn't a formal requirement, witnesses are. Under the Code of Inheritance a will is valid when it is made in writing, signed by the testator, and two impartial witnesses are simultaneously present at the signing or its acknowledgment. The witnesses must know the document is a will, though its contents need not be shown to them — and they must be at least 15. Disqualified are beneficiaries and the close relatives and spouses of the testator or a beneficiary: this is where most home-made wills collapse. Content has one hard limit, the reserved share: a direct heir always keeps the right to half of their inheritance share, whatever the will says.
📋 The rules
- Formal requirements: written form, the testator's signature, and two impartial witnesses simultaneously present at signing or acknowledgment.
- Witnesses must be 15+ and impartial: not beneficiaries, nor their or the testator's close relatives or spouses.
- Witnesses must know it's a will — contents can stay private; good practice adds an attestation clause with dates.
- Direct heirs' reserved share (half of their statutory share) survives any will — claimed within the statutory period.
- Store the will safely (safe-deposit box, personal archive) and tell someone you trust — no registry exists.
🔓 Exceptions
- An emergency will (oral before two witnesses, or holographic without witnesses) is possible but lapses three months after the impediment ends.
- Spouses' mutual wills are common and follow the same formal requirements.
- A will isn't registered anywhere — store the original safely and tell someone you trust where it is, because a copy is in principle not enough.
⚠️ Penalties
A will with formal defects can be declared invalid on challenge, and then the estate passes by law — not by your wishes. The classic errors are a disqualified witness (a beneficiary or their close relative) and witnesses signing at different times: either one topples the document no matter how clear your intent was. The dispute is then fought out between the heirs in court, at the estate's expense. The other typical stumble is the reserved share: a direct heir can claim half of their statutory share within the deadline, shrinking the will even when it is formally flawless.

❓ Frequently asked questions
Is a handwritten will valid?
Yes — handwritten or typed both work, as long as the document is written, signed, and two impartial witnesses were simultaneously present. The form decides the matter, not the writing instrument.
Who cannot act as a witness?
A beneficiary, their or the testator's spouse and close relatives, and anyone under 15. A neighbour or a colleague is typically the safe choice — leave relatives out of it entirely.
Can I disinherit my child?
Not as to the reserved share: a direct heir can always claim half of their statutory share. Full disinheritance requires a weighty statutory ground, such as a serious crime against the testator.
Must the will be registered?
No — there is no registry. Store the original safely, for instance in a safe-deposit box, and tell someone you trust where it is; a copy is in principle not enough to execute the will.
Does an oral will work?
Only in an emergency: an emergency will can be made orally before two witnesses, or in your own hand without witnesses. It lapses three months after the impediment ends, so it is a stopgap, not a plan.
