Quick answer: the biggest delay risk beyond the 8-month floor is contested Court of Chancery litigation, followed by a late accounting and real estate sales. Estimate your own timeline with the Delaware probate timeline calculator.
1. Contested Court of Chancery proceedings
2. A late accounting
Delaware backs its accounting deadlines with a real financial consequence: the court can reduce the executor's commission if required accounts aren't filed on time. Beyond the direct cost, resolving a late or disputed accounting itself takes time before the estate can safely close.
3. Unresolved state tax paperwork
No executor commission is allowed until certain state tax-filing requirements are satisfied. While this gives the executor a strong incentive to handle tax matters promptly, working through them can still add administrative time before the estate is ready to close.
4. Selling real estate
Property that needs to be listed, sold, and closed before the estate can distribute proceeds typically runs longer than the 8-month creditor bar, and often becomes the actual bottleneck.
