This discussion concerns a property inherited from a grandfather who died intestate. A relinquishment deed was signed between the father and his elder brother, favouring the father. However, the father's three step-sisters did not sign this deed. The key question is whether these step-sisters, or their sons, can claim a share of the house. Experts advise that since the grandfather died intestate, his legal heirs, including the father's sisters, have a right to their share. It is strongly recommended to amicably settle the matter with the step-sisters before proceeding with any construction plans, such as building a four-floor office.
