It appears Jodie Sweetin's third marriage will be short-lived.

The "Full House" star filed papers Monday seeking legal separation from husband Morty Coyle, according to various online reports.

The couple married in March 2012 but only recently revealed details of their nuptials on their one-year anniversary, March 15, 2013.

Sweetin's rep declined to comment to ABCNews.com, but on the day she reportedly filed for separation, Sweetin tweeted: "Hope you are all having an awesome Monday! A new week, a new beginning :)."

Sweetin, 31, is asking for full custody of their daughter, Beatrix, 2, according to the court papers obtained by TMZ.

She also wants their 2000 Toyota Avalon and is asking that they split their $200 Kohl's credit card balance, the website reported.
