Are villa and land owners who refrain from paying the agreed-upon maintenance fees to the General Assembly considered sinful?

Maintenance and security work in residential complexes that prevent harm and benefit all owners should be distributed among them. The fundamental principle is the obligation to fulfill contracts and adhere to recognized conditions. It is sinful for anyone to benefit from services without paying the equivalent. A partner is compelled to carry out construction with his co-owner in shared property if harm is feared, based on the Prophet's (peace be upon him) saying: "There should be no harm nor reciprocating harm." If shared property requires essential construction, one of the partners must build with his co-owner.
