Legal analysis: the legal heir certificate requires the heir to show his identity card, household registration book, marital status certificate and decedent to the neighborhood Committee or village Committee where the deceased was registered before his death, and first issue a certificate of kinship. Then, with the above documents and written materials, go to the household registration management police station where the deceased was registered before his death, issue the kinship relationship between the heir and the decedent, and affix the official seal of the household registration management of the police station. In addition, when inheriting the inheritance of parents and other related personnel, it is necessary to carry out inheritance notarization. Under normal circumstances, if there is only one party in the first succession order, it can be proved that it is the sole heir of the property. On the other hand, if the first order has more than one heir, it is not the only heir. At this time, if you want to be the sole heir, you must have a written promise that equal heirs will give up their inheritance rights. To prove the legal heir, the heir needs to show his identity card, household registration book, proof of marital status and decedent to the neighborhood Committee or village Committee where the deceased was registered before his death, and first issue a certificate of kinship.
