Family trust is a trust fund established by family members to manage and protect family property. Although family trust is a very useful financial management tool in some cases, it is not suitable for everyone. The following are some situations that are not suitable for setting up family trusts: First, family trusts are not necessarily suitable for people with unstable family financial situation. For example, if the household income is unstable or the household debt is high, it may not be able to bear the high cost of setting up a trust. Secondly, if there is tension or distrust between family members, the establishment of family trust may aggravate this bad relationship. Because family trusts usually need close cooperation between family members, if there is a problem in cooperation, then family trusts may not operate normally, resulting in the loss of family fortune. Finally, if the number of family members is small, it may not be necessary to set up a family trust. Family trusts usually need a certain number of members to make full use of their potential advantages, such as reducing the tax burden and increasing the security of family fortune.
