The answer to this question really depends on the jurisdiction you are in. In Colorado, you would likely qualify for maintenance because for a marriage of this duration, court generally believe that it is equitable that both parties have the same standard of living. Other jurisdictions look at spousal support differently - some basically do not offer much maintenance and others only assess whether or not you have enough income to meet your basic living needs. In most states, inheritances or other gifts are considered separate, except to the extent that they have increased in value over the duration of the marriage. In considering whether or not you are entitled to half of his retirement, the answer generally would be yes - but with the caveat that he would likely be entitled to half of your retirement as well, and generally courts offset these entitlements. Colorado has equitable jurisdiction though, so if there is a reason one or the other of you might need more than half (as might be the case if one of you is disabled and has greater costs) then the court might deviate from a strict 50-50 division.
