Tom Bonner is leaving Ebbsfleet United to rejoin their local rivals Dartford.
The centre-half captained Fleet last season but will leave the club when his contract expires at the end of June.
Bonner, 28, becomes Dartford's first signing of the summer.
Dartford manager Tony Burman said: "I am delighted to have Tom back on board for next season.
"He will be a excellent addition to the squad and he has now gained a lot more experience from his time at Cambridge, Dover and Ebbsfleet since leaving us three seasons ago.
"Tom is a good defender and has the hunger to succeed, and I have no doubt that Tom will help the club achieve their targets over the next couple of seasons."
Bonner was a fans favourite during his first spell with the Darts but left in May 2013 alongside team-mate Tom Champion to pursue a full-time career with Cambridge United.
He suffered with injuries during his time with the U's and was loaned out to Dover at the start of the 2014/15 season.
Bonner was part of the Whites side which reached the FA Cup third round that season but agreed a permanent move to Ebbsfleet in January 2015 following Jamie Day's appointment as manager.
Fleet finished eighth in Conference South but spent most of last season top of the table, with Bonner starting 36 of their league games.
However, he was dropped for both legs of the play-off semi-final against Whitehawk and although recalled for the final against Maidstone, he had to play at right-back for the first time in his career.
Bonner will now line up against Daryl McMahon's side in a white shirt next season.
