The line
The Dorchester–Berkeley county line runs roughly along the old town's eastern and northern edges. The communities built since I-26's exit 197 opened—Nexton, Cane Bay, Carnes Crossroads, Sangaree, much of the 29486 ZIP code—are in Berkeley County. So is Jedburg. Historic downtown Summerville, Knightsville, Ashborough, Old Trolley Road and most of 29483 and 29485 are Dorchester County. Your property tax bill, your voter registration card and the county GIS map all say which side you are on.
What the county decides
| Matter | Dorchester side | Berkeley side |
|---|---|---|
| Probate of an estate | Dorchester County Probate Court, St. George | Berkeley County Probate Court, Moncks Corner |
| Guardianship or conservatorship | Dorchester County Probate Court | Berkeley County Probate Court |
| Recording a deed or power of attorney | Dorchester County Register of Deeds | Berkeley County Register of Deeds |

| A felony charge | Dorchester County General Sessions, St. George | Berkeley County General Sessions, Moncks Corner |
| Bond hearing after arrest | Dorchester County Detention Center, Hodge Road, Summerville | Hill-Finklea Detention Center, Moncks Corner |
Inside the Summerville town limits—which also cross the county line—Summerville Municipal Court hears town-police tickets and ordinance cases regardless of county.
Why it matters for planning
Estates are probated where the person was domiciled at death, so a Cane Bay retiree's estate goes to Moncks Corner even though every relative assumes Dorchester. A durable power of attorney is recorded in the county of residence. And when families file in the wrong court, the case is dismissed and refiled—weeks lost during a hard time. Our guide to the three probate courts has addresses and phones for each.
Why it matters for a charge
Which sheriff's office made the arrest and which solicitor's office prosecutes are county questions too, although Dorchester and Berkeley share the First Judicial Circuit solicitor. Jack appears in both counties' courts; see Nexton, Cane Bay and Carnes Crossroads for the specifics.
Frost first: if you are opening an estate for someone who lived in a 29486 address, check the county before you file anything. It is the single most common wrong-court filing we see.
