English to Spanish Law/Patents Law (general)

I have a list of ‘events’ that occur in people’s lives, in the context of an on-line genealogy software:

Items in the list include:

Birth
Baptism
Will
Death
Burial
Probate
etc

where ‘probate’ is the legal process of proving the validity of a will.

My Spanish dictionaries only give long-winded explanations, such as 'verificación oficial de los testamentos' (Collins eng/esp), not short one-word translations (two words at most) that will fit in a drop-down menu on the website.

Target: Southern Cone + Spain

I don’t necessarily need an exact translation – a short phrase that could be construed as implying ‘probate’ or equivalent/similar acts in South American jurisdictions would be an acceptable alternative, since this website is primarily for genealogists, not lawyers.
