I've been working on an estate legal program for a couple from central Louisiana. It's a "his, hers, and ours" scenario. The wife has several children from prior marriages. The husband has one child of his own. After they married, they had another child. They mentioned several times that they were not very close with the older children, and that many of the older children had a larger estate than this couple had.
Their main concern was for their youngest child - that they had together. The wife was concerned that they may be forced to leave an inheritance to the older children due to Louisiana's forced heirship laws, but we discussed that since the older children were older than 23 years of age, she was not forced to leave the older children an inheritance. They realized that the youngest child was a forced heir, but the fact that the youngest child was a forced heir was not an issue because they would leave the bulk of their estate for the benefit of this youngest child.
They wanted an arrangement where the surviving spouse would completely control everything. But after both the husband and the wife pass away, they want their estate to be for the benefit of their youngest child. This child, a daughter, while responsible, would not be prepared to inherit an estate in a lump sum. But the couple had no family member or no one else that they could "trust" enough to be the Trustee of their daughter's trust after the couple passes.
After discussing the pros and cons of naming a corporate trustee to handle things for the young child (if the child happens to still be young when the couple dies). They selected the trust department of one of the national banks that they use to be the trustee.
Now the couple knows that if they pass away before their child completes all of her graduate and post-graduate education, then their estate will be managed by professionals and used for the right reasons until the child is an adult and has the maturity to handle the inheritance prudently.
The couple now knows that they have taken the necessary legal action to set up an estate legal program to protect the surviving of them from children or other who may want to cause a fuss, and they've provided for the financial well-being of their child who will need a head start on life if her elderly parents pass away unexpectedly in the next several years.
