No one likes to think about the possibility of divorce. Unfortunately, however, it does occur, leaving emotional and financial uncertainty in it's wake. As with any major life change, attention needs to be paid to your financial plans and goals.
Due to the emotional nature of divorce, it can be hard for some people to concentrate on the financial aspects of their life. However, as hard as it may seem, some decisions need to be made regarding savings, housing, etc.
If you have children, you will need to work out a financial plan with your ex regarding support. You will also need to factor in such expenses as post-secondary education, and arrange some sort of savings plan in order to provide for future expenditures. Also consider such items as vacations, car insurance for teenagers, etc. Both parents should have life insurance in order to protect the children's financial interests should something happen to one of you.
If you are just recently separated, do not rush out and purchase a new home. Rent for a few months, and house hunt, but avoid the impulse purchase. Buying a home that you later decide you don't like, or have decided to move to another area, etc. can seriously affect your finances. Allow yourself some time to get acclimated to your new situation, and avoid making any big purchases. Wait until you are more certain of what's in store for yourself, and then make a decision on home buying. If you are planning on selling the marital home that already has a mortgage, you may find it hard to acquire a new mortgage until the first has been settled.
Obviously, you will need to make a new financial plan, based on your earnings, not the combined earnings you had. Re-evaluate your spending habits as well, they should reflect only your income. Many people find themselves deeply in debt when they keep spending the same amount, but with only half the income coming in. As well, consider your long term financial goals, with a view towards retirement. It's advisable to consult with a financial planner at this point in order to ensure a secure financial future for yourself.
Both parents can purchase term life insurance policies that are specifically designated for the care of their children in case of death. Both parents can buy term life in an amount that takes care of the children until they are adults. Disability insurance is a good idea as well, as there is only one income in the house. Should you become ill or get injured, you will need to still have money coming in to take care of the household responsiblities.
