Modern Family creator Steven Levitan’s estranged wife, Krista, claims the director-writer-producer earns over $2.4 million each month before taxes, and puts away about $1 million into a savings account monthly, according to court docs, TMZ reports.

Krista, 51, filed for divorce citing irreconcilable differences, according to separate divorce papers filed Jan. 6 obtained by PEOPLE.

According to the filing, the pair was separated as of Dec. 31 – and Krista is asking Steven, 53, to pay both spousal support and attorney fees.

The pair was married for 23 years. They have three adult children, Alexa, Hannah and Griffin.
