Jane Lynch's Estranged Wife Lara Embry -- I Want More Spousal Support!

Jane Lynch and Dr. Lara Embry's "amicable" divorce just turned "unfriendly" ... because Embry is making a full-court press for Jane's bank accounts -- to the tune of $93,809 a month in spousal support!

In new legal docs, obtained by TMZ, Embry says for the last 3 years, Jane's average monthly income has been $234,688. Embry also says when she married Lynch, Jane told her she had $400,000 in her savings and 401K combined, and owned her home.

Embry says of her "Glee" wife, "Her income, investments and assets increased dramatically with her newfound acting success."

Embry -- who says she wants Jane to support her in the lifestyle to which she gladly became accustomed -- says during their marriage Jane paid for everything, including lavish vacations.

Embry says she and Jane typically racked up $40k a month on their credit cards.

According to Embry's docs, she currently earns pennies, but still spends in the neighborhood of $40,900 per month -- including an average of $6,500 on clothes, $12,000 on entertainment/gifts/vacation, and $4,500 on eating out (hehe).

Sources tell us ... Jane is already providing Embry with support. In fact, Embry and her daughter are living in the house Jane bought and Jane temporarily moved elsewhere. But the house is a big sticking point. Embry says they sunk $3 mil into the house for renovations and from the docs it seems she either wants the house or a 50% cut.

Sources tell us the couple did not have a prenup, which means assets acquired during the marriage will probably be split 50/50.

Jane filed to end her three-year marriage to Lara in July, citing "irreconcilable differences." The two first met in 2009 at a fundraiser in San Francisco. They were married a year later in Massachusetts.

Jane said recently the financial negotiations have been friendly, adding, "It's just money." Right.
