Couples in a second marriage face issues different than couples in their first marriage.

1.  How to balance the  financial needs of the new spouse with the expectations of children from the first marriage.
2.  When the second spouse is close in age to the children, how to provide for the spouse without making the children wait their entire lives for an inheritance.
3.  Who/what to designate as the beneficiary of retirement assets and insurance policies.

Of course, like many topics on this blog, these issues can be addressed through the use of a trust in an estate plan. A prenuptial agreement is also important when there are children from a prior marriage.
