The court fee for the application is 100 złoty. On top of that comes an advance on expert opinions, the amount of which is set by the court, and a lawyer's fee if you use one. Someone whose financial situation does not allow those costs can apply to be exempted from court fees.
No notary is involved
Incapacitation (ubezwłasnowolnienie) is decided by a regional court, and only by a court. A notary office does not handle such cases, so the question of what it costs “at a notary” has no answer. If you are looking for something that can be arranged at a notary office within an hour, what you probably need is a power of attorney rather than incapacitation.
What the bill is made of
The application fee is 100 złoty. The rest depends on how the case unfolds.
The court relies on expert opinions and may call on the applicant to pay an advance towards the costs of that work. The amount is set by the court and depends on the number of opinions, the scope of the examinations and the course of the proceedings. There is no official rate that could be quoted in advance, so any specific figure circulating on forums describes one case rather than all of them.
The third item is a lawyer. Legal representation is not compulsory, and the fee is a matter of the agreement with the client.
Exemption from costs
Someone whose financial situation does not allow those expenses without harm to their own or their family’s upkeep can apply to be exempted from court costs. The application goes in together with the main one, with a statement of family circumstances, assets and income attached.
Before counting the cost, check whether this is the right route
Incapacitation is the furthest-reaching option: it removes or limits the capacity to perform legal acts and closes the door to making a will. In many situations where a family considers it, a power of attorney prepared in advance or a curatorship is enough. The cost is then several times lower, and the decision stays with the person it concerns.
