London & Co, a US accounting firm, has been caught up in divorce proceedings between a popular Grey's Anatomy actress and her estranged husband. Alex Young, who separated from the popular hospital drama's actress Kate Walsh, has filed papers requesting a Los Angeles court to order the firm to reveal financial records related to the matrimonial home and bills, which went to the firm since it acted as their tax advisers and business managers during his marriage to Walsh. Young, a 20th Century Fox studio executive, married Walsh in September 2007 but filed for divorce 14 months later, claiming irreconcilable differences, WebCPA reports. The Santa Monica-based firm holds the financial records related to the purchase of the couple's house, expensive artwork and furniture, for which the couple paid millions of dollars using both of their earnings, and the payment of bills. Following the decision to divorce, Young moved out of the home in November, and from December into January continued to ask the accounting firm to provide him with documents about the house and payment of expenses for it. His petition said: 'London & Co was very slow to respond and it would not answer certain questions that Mr. Young [asked] it about the payment of expenses and the way that London & Co. continued to use Mr Young's earnings, which were still being deposited into accounts by London & Co'. But the firm, which had already been at loggerheads with Young earlier in the year, sought an order of protection.In court papers, the firm said that in February, before it knew of Young's court action, it sent 'accounting ledgers fully reflecting every accounting transaction for Walsh, Young or any related corporate entities that London ever worked on' which consisted of over 500 pages. However, Young 'continues to harass London through written correspondence and baseless threats'. London & Co told the court that it had sent about 3,000 pages of documents to Young's attorneys.
