The developer from Westbrook who planned to build a high-end retail, office and recreation complex on Stroudwater Street is being sued again by the son of his late partner in the project.

In a complaint filed May 18 in Cumberland County Superior Court, David Emil, son of the New York City developer Arthur Emil, claims that his father loaned Jason Snyder more than $345,000 that he hasn’t repaid, and that Snyder owes Emil’s estate about $417,000, including interest.

“The allegations are without merit and, when all the facts are known, there will be no finding of liability,” Snyder wrote in an email Monday.

Emil’s attorney, Eric Wycoff of Pierce Atwood, did not return a phone call seeking comment.

Snyder and Arthur Emil proposed in 2008 to build a 1.65-million-square-foot development on Snyder’s land off Stroudwater Street.

The complaint says ownership agreements for that property and a piece of land in Portland allotted Snyder an 80 percent share and Emil a 20 percent share of each property.

Emil loaned Snyder money to cover his share of the development expenses, the documents say.

Since Emil’s death in August 2010, Snyder and the estate have not been able to reach an agreement about developing or selling the properties, and Snyder has refused to repay the loans, according to the complaint.

David Emil, who controls the estate, and Oded Aboodi, a New York businessman who controls Arthur Emil’s trust, filed a complaint in October seeking to dissolve 500 Westbrook LLC, the company that Emil formed with Snyder.

That complaint said the company owed nearly $2.5 million to its mortgage holder and other creditors. The company filed for bankruptcy in November.
