The laws related to property and inheritance can vary significantly depending on the country and jurisdiction. Therefore, it's essential to consult with a qualified legal professional who is familiar with the laws in your specific area to get accurate advice.
In many places, when parents give their house to one son, it may be considered a gift or a transfer of property ownership. If the parents want to ensure that both sons receive a share of the property, they may need to take specific legal steps, such as creating a will or a trust, to divide the property equitably between the two sons.
If there is no legally binding agreement or estate planning in place, it's possible that the son who received the house could become the sole owner of the property. In such cases, the unmarried son may not automatically have a legal right to a share of the property unless the laws in the jurisdiction provide for specific inheritance rights for close relatives.
In some regions, there might be laws that grant certain inheritance rights to close relatives, such as children, even if they are not named in a will. These laws typically vary, and they may grant a portion of the estate to the unmarried son, but the specific rules will depend on the local laws.
Again, it's crucial to seek legal advice from a qualified attorney or legal expert who can guide you through the relevant laws and ensure that everyone's rights and interests are protected. Estate planning and inheritance matters can be complex, and professional guidance can help ensure that the parents' intentions are carried out in a fair and legally valid manner.
