A Jewish congregation that caused a neighborhood ruckus when it obtained permission from Boca Raton to build a synagogue and Israel museum fears it may not get the land it claims it was promised for its new home.

In a complaint filed in Palm Beach Circuit Court, the Chabad of East Boca Raton said Irving Litwak, a devoted congregant, planned to donate 0.84 of an acre at 770 E. Palmetto Park Road, east of the Intracoastal Waterway. Litwak set up the TJCV Land Trust, which acquired the property in 2009 for $2.7 million.
