F » Forced Heirship Rules
Forced Heirship Rules apply in foreign countries where rather than having a system of testamentary freedom (like in England & Wales) allowing citizens to make Wills and give their Estate to whomever they choose, Forced Heirship means that, with or without a Will, the Deceased's Estate MUST go to certain people - normally spouse & children - in certain proportions.
In other words, you cannot prevent it happening that way. Unless that is you have made more complicated plans in your lifetime, in which case your lawyer will help you further.
