what is forced heirship?

Answer 1

The following is from Wikipedia:

"Forced heirship is a reference to the testamentary laws which limit the discretion of the testator to distribute assets under a will or codicil on death. Forced heirship laws are most prevalent amongst civil law jurisdictions and in muslim countries, but also occurs in other major countries such as France, the U.S.A. (in Louisiana) and Japan."

You can read the rest of the Wikipedia article about forced heirship at the first link below. The second link is a PDF explaining the Louisiana law on forced heirship, which I think explains the concept more clearly.

Good luck!
