Currently, our wealth.com documents allow for a single primary executor (and provides the ability to also name backup executors).
One bit of context worth sharing: many estate attorneys actively counsel clients away from co-executors, even when adult siblings are involved, because co-executors typically must act jointly — meaning both signatures on probate filings, tax returns, bank forms, and asset transfers. That can introduce real delay during administration, particularly in jurisdictions where probate is more procedurally heavy. It doesn't mean co-executors are wrong for every family, but it's part of why we haven't prioritized it yet. For those who feel strongly about co-executors, our attorney network can handle that as custom drafting.
