Look for letters or notes asking someone to defer his income. Look at past history of your husband's earnings. Your attorney can use this information. Some companies offer very little to none, while other companies' perquisites are so valuable that they almost equal the salary being paid. Your husband may be alleging that the company provides the car for business use only and if he uses it for personal use, he must pay back the company.
Some companies pay all or a portion of their employees' monthly parking rates.
Your husband may tell you that he pays his own parking expenses. He may even pick up parking receipts off the floor of the parking garage or make a deal with one of the parking attendants to give him extra receipts. Expense accounts range from small to large. Your husband may have an expense account to take customers to fancy restaurants, sporting events and other, areas of entertainment. Look at the documents to see whether he is taking clients to Burger King or other inexpensive restaurants and keeping for himself a portion of each weekly expense account.
