If the daughter-in-law is particularly concerned about surnames, let the children take their own surnames. This is the daughter-in-law's free mother-in-law has no right to interfere, but the mother-in-law has the right to dispose of her own property, which is also the daughter-in-law's right to interfere.
On the other hand, it is not a healthy attitude for a daughter-in-law to think about her mother-in-law's property. The mother-in-law gave her daughter-in-law the right to choose. If the daughter-in-law attaches great importance to the child's surname, she must let the child take her own surname. This is her choice, and as a result of this choice, children with foreign surnames will not leave a legacy; Or the daughter-in-law is willing to let the child take the father's surname, then the child can get the property.
People are faced with choices all the time, and everyone has to pay the price for their choices. No problem. As a mother-in-law, the husband's surname is rare, and the mother-in-law hopes that the incense can be passed down, so she hopes that the child will take the father's surname.
It is true that many surnames are getting less and less. Family planning, children follow their father's surname, resulting in fewer and fewer surnames. Even if it is not a rare surname, it is no problem for the mother-in-law to leave her property to her father's descendants. The donor has the right to decide the object of the gift.
Moreover, no one stipulates that the older generation must give property to the next generation. Only in traditional culture, parents are always giving. They not only raised their children, but also left them wealth when they left. This culture is actually morbid.
