What Delays Probate in Connecticut?

Because the creditor clock only starts once someone is actually appointed, the single biggest lever a family controls in Connecticut is how quickly that petition gets filed.

C.G.S. Title 45a; § 12-391

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

The stakes: because the 150-day period under C.G.S. § 45a-356 doesn't begin until the Probate Court appoints the first fiduciary, every week that passes before someone files that petition is a week added directly onto the earliest point at which the fiduciary can safely make distributions. A slow start pushes the whole schedule back one-for-one, the same dynamic seen in a small number of other appointment-triggered states.

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.

What delays Connecticut probate — frequently asked questions

Does waiting to petition for a fiduciary delay a Connecticut estate?

Yes, directly. Since the 150-day creditor period doesn't begin until the Probate Court appoints the first fiduciary, every week spent before filing is a week added to the earliest point at which the estate can safely distribute assets.

Does the mandatory estate-tax return delay Connecticut probate?

It can add work even for a small estate, since every resident decedent's estate must file a return within 6 months of death regardless of whether tax is owed. For a taxable estate, valuing non-probate assets correctly for the return can add real time before the estate is ready to close.

Does a contested estate delay Connecticut probate?

Yes. 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, pushes back everything downstream as well.

Does real estate delay Connecticut probate?

It can, especially since real estate value is folded into the same gross-estate calculation used for the mandatory estate-tax return and the Probate Court fee — getting an accurate appraisal in place is part of the critical path, not a side task.

Estimate for general guidance only, not legal advice. Whether a specific estate will actually be delayed depends on its own facts. Consult a licensed Connecticut attorney about a contested or complex estate.
