Utah's attorney general is demanding a settlement in a nearly 5-year-old dispute over a communal land trust once held by a polygamous church.

The United Effort Plan Trust holds most of the property and homes in Hildale, Utah and Colorado City, Ariz., where members of the Fundamentalist Church of Jesus Christ of Latter Day Saints live.

The trust has been under state control since 2005 after allegations of mismanagement. Settlement talks last year failed.

In a letter sent to FLDS attorneys, Mark Shurtleff says the issue must be resolved within 30 days. He suggests following a proposal from Bruce Wisan, the accountant appointed by a judge to manage the trust.

An attorney for the FLDS says the demand is inconsistent with ongoing settlement talks.
