Is it a bad idea to name two children as coexecutors?

In the estate planning context, naming alternates is important. Local law matters in disputes involving probate, trusts, title, and family rights, so have a lawyer in the state confirm the governing documents and the present court or title status before anyone does something that cannot easily be undone. Look for a fiduciary who is trustworthy, organized, available, willing to serve, and able to handle conflict.
