Legal analysis: If a father refuses to pay back his daughter's money, the handling method is as follows: 1. If the father deliberately refuses to pay back his daughter's money, the two sides can negotiate to get the money back first and urge him to pay it back in time; 2, keep the corresponding loan credentials, and then as a debt dispute, sue the defaulting party to the court and ask the debtor to pay the corresponding interest; 3. At the same time, the daughter can inquire about the property status under the other party's name or apply to the people's court for preservation.

Legal basis: Article 100 of the Civil Procedure Law of People's Republic of China (PRC), the people's court may, on the application of the other party, order the preservation of property, order it to do certain acts or prohibit it from doing certain acts, if the judgment may be difficult to execute or cause other damage to the parties.
