What is the crucial date for determining the length of a relationship when considering spousal support?

The crucial date for determining the length of a relationship when considering spousal support is the date of separation. This date is significant because it marks the end of the marital partnership and the start of the assessment for support obligations. In spousal support cases, the length of the relationship is often calculated to understand the duration for which support might be warranted, as longer relationships typically result in a greater expectation of support.

The date of marriage is often relevant in family law for various matters, but it does not reflect the point at which the dynamics of the relationship might have changed significantly leading up to the need for spousal support. Likewise, the date of first cohabitation can also hold importance in assessing the relationship's context but does not take precedence over separation when considering ongoing financial support. Similarly, the birth of the first child is generally linked to issues of child support and custody, rather than explicitly defining the terms of spousal support. Thus, the date of separation is the pivotal factor in these evaluations.
