11:35 AM PT -- According to the divorce docs, obtained by TMZ, LaMarcus agrees to pay Brittany 30% of his income monthly in alimony, cover the first 6 months of her rent and make sure her new place is furnished and their kids have a safe, stable environment.
The couple's also worked out custody of their 2 kids -- they'll stay with him a minimum of 5 nights a week because she works nights, but if anything changes he'll pay for childcare and get the kids on weekends. The judge has yet to sign off on the agreement.
"Friday Night Lights" and "Glee" actor LaMarcus Tinker and his wife Brittany, are dropping back and punting on their marriage.
According to court records from Washoe County, Nevada ... LaMarcus and Brittany on Wednesday filed a joint divorce petition. It's unclear what led to them calling it quits, but it's the end of a 5-year run as husband and wife. The estranged couple has 2 minor children together.
LaMarcus -- best known for playing Dallas Tinker on the hit NBC series -- has been down this road before. As we first reported, he and his previous wife, Shari Butler, also filed a joint petition to end their 2-year marriage back in 2014.
Back then, LaMarcus was earning around $2,100 a month, just in royalties from previous acting gigs. Besides appearing on 'FNL' ... he played Kevin on the ABC sitcom "Cougar Town" -- and also had the recurring role of Shane on the third season of "Glee."
With marriage #2 coming to an end, this might be a good time for a throwback to that classic 'FNL' mantra -- "Clear eyes, full hearts ... can't lose."
