My friend happens to hold a land title about 4,000 sq.M. The land title is from her deceased mother. In the Land Title she is holding it says: "sa lahat ng makatutunghay ng Kasulatang ito, Bati, heirs of (the name of my friend's mother) represented by (my friend's name). Her mother has no legal spouse, nonetheless, her mother was able to had two (2) communal relationship (no legal binds). Her mother was in a communal relationship with her father and had 8 children including my friend as the eldest. When their father died, her mother enter into a new communal relationship and had 2 more children. All in all, they are 10 children, 8 from the first relationship including my friend and 2 to the latter relationship.
Now, her mother and the two fathers of her children are already dead. However, some of children are still surviving, including my friend. My friend occupies a portion of this land and built a house on it. While some other portion of the land was occupied by other families (no blood relationship with her mother). According to these alien occupants, they are paying a lease/rent to one of my friend's nephew (from the latter relationship of her mother) without the direct consent to her.
This nephew of her becomes so arrogant, in fact, claiming the whole land as theirs when they can not even provide a proof. This nephew even had the nerve of telling my friend to destroy their house and leave the land premises.
1. Does my friend have a legal right to stay in the land of her mother?
2. If she does have the right? what portion of the land can she claim legally?
3. Some of her siblings are no longer interested in the land giving their fare share to her? how can she possess these shares of her disinterested siblings legally?
4. To what extent is the right of her nephew to the land of her mother.
Thank you very much in advance. I hope i could get legal opinions and advice so I can relay it to my friend. By the way she is an ordinary farmer who can barely read and write. It is my deepest sympathy in helping her.
