David Tutera -- the host of "My Fair Wedding" -- followed the biblical path in his split with Ryan Jurica -- he gets one of their twins, and Ryan gets one.
The two men had a 10-year domestic partnership that blew apart in January ... and it got UGLY. And there was a big complication -- they had fraternal twins through a surrogate in July, and that triggered a bitter custody battle.
Now here's the complication. Each man fertilized an egg that was then implanted in the same surrogate, who gave birth to the two babies at the same time. It appears the eggs are from the same biological mother.
Sources familiar with the situation tell TMZ ... a judge has issued a temporary custody arrangement in which David gets custody of his biological child, baby girl Cielo, and Ryan gets custody of his biological child, Cedric.
We're told David and Ryan are "close" to a final settlement, where the temporary custody arrangement will become permanent.
We're also told the two men are getting along. It's unclear if they will each get visitation rights of each other's kid. So we gotta ask ...
FYI, Tutera had a chance to explain himself on "The View" this morning. Check the clip.
