Quick answer: the biggest delay risk in Connecticut is waiting to petition for a fiduciary, since that delays when the 150-day creditor clock even starts. The mandatory estate-tax return and a contested estate are the next most common causes. Estimate your own timeline with the Connecticut probate timeline calculator.
1. Delaying the fiduciary petition
2. The mandatory estate-tax return
Because every resident decedent's estate must file a Connecticut estate-tax return within 6 months of death — even a modest estate with no tax owed — there's real paperwork to do regardless of size. For a taxable estate, or one where the Probate Court fee basis (which can include non-probate assets) needs careful valuation, getting that work done accurately can add meaningful time before the estate is ready to close.
3. A contested estate
A will contest, or a dispute over who should be appointed fiduciary, can delay the appointment itself — which, given Connecticut's appointment-triggered creditor clock, delays everything that follows as well. Once contested, a matter moves into litigated territory well beyond the standard administrative timeline.
4. Real estate and complex asset valuation
Because Connecticut's estate-tax return and Probate Court fee both hinge on an accurate gross-estate figure, real estate appraisal and valuation of any non-probate assets included in that figure are part of the critical path, not an afterthought — delays here can hold up both the tax filing and the final closing.
