Colorado uses the Income Shares Model to calculate child support. This model combines the gross incomes of both parents to determine a basic support obligation, which is then divided proportionally based on each parent's income share. The calculation considers the number of children and adjusts for factors like parenting time, healthcare, and childcare costs. The state uses two worksheets: Worksheet A for sole physical care (92 or fewer overnights for one parent) and Worksheet B for shared physical care (more than 92 overnights for both parents).
A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.
Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.
If the custody schedule changes significantly, support can be recalculated under Colorado guidelines.
Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.
Common questions
An uncontested divorce in Colorado can be finalized in as little as 92 days due to the mandatory waiting period. Contested divorces typically take 6-9 months or longer, depending on the complexity of issues such as property division, child custody, and support.
No, you are not legally required to have a lawyer to get divorced in Colorado. Individuals can file for divorce 'pro se' (representing themselves). However, it is generally recommended to consult with an attorney, especially in cases involving complex assets, debts, or child-related matters, to ensure all legal requirements are met and your rights are protected.
Yes, Colorado is a no-fault divorce state. The only legal ground for divorce is that the marriage is 'irretrievably broken,' as stated in C.R.S. § 14-10-106. This means neither spouse needs to prove fault or misconduct (such as adultery or abandonment) to obtain a divorce.
Colorado follows the principle of equitable distribution for dividing marital property and debts. This means that marital property (assets and debts acquired during the marriage) is divided fairly, but not necessarily equally, between the spouses. Separate property (acquired before marriage or by gift/inheritance) is generally retained by the owning spouse. The court considers various factors to determine a just division, as outlined in C.R.S. § 14-10-113.
Colorado law mandates a minimum 91-day waiting period after the petition for dissolution of marriage is filed (or after service of process on the respondent) before a divorce decree can be issued. This period, specified in C.R.S. § 14-10-106(1)(a)(III), is intended to allow for reflection, potential reconciliation, or the finalization of settlement agreements between the parties.
