Lao Wang has a son and a daughter. He gave all his property to his son and daughter-in-law without telling her. Is it legal for her to ask Lao Wang's daughter to support the elderly now?

It is also legal for the daughter-in-law to ask Lao Wang's daughter to support the elderly, but according to the truth, they all inherited the real estate, so they should take care of the elderly and need to support them more. The daughter didn't get the real estate, but the daughter was born to her father, and the old man had to support her.
