As a seller, Party B signed a contract with Party A, which stipulated that Party B must assist in the transfer of property rights to Party A's name. Therefore, according to the contract, B must handle the transfer formalities as a house for sale.
Now that B is dead, B's obligations must be fulfilled by B's heirs, that is, B's children. B's children also signed a contract and recognized it by their fingerprints, so they must inherit the obligations stipulated in the contract. If they are unwilling to inherit the obligation, they must give up the interests related to the obligation, and they will not be able to inherit the part of the property purchased by A.
It is suggested that A hire a lawyer to file a lawsuit against B's children and demand them to fulfill their obligations. At present, A's lawsuit is within the validity period.
Litigation period with interest infringement: Article 137 of the General Principles of Civil Law stipulates that "the protection of rights by people's courts shall not exceed 20 years from the date of infringement". According to this provision, the longest limitation of action is calculated from the date when the right is infringed. The obligee does not know that his rights have been infringed, and the longest limitation is 20 years. If it has been more than 20 years, the people's court will not protect it.
