Your question, explained
Montana does not have a mandatory waiting period after marriage before filing for stepparent adoption — but there are practical timing considerations.
What IS required:
- You must be legally married at the time of filing (Mont. Code Ann. § 42-1-103)
- You must meet the 0-month residency requirement in Montana
What is NOT required:
- No minimum length of marriage before filing
- No requirement to have lived together for a specific period
- No waiting period after the wedding date
Practical considerations:
- If you recently moved to Montana AND recently married, the residency requirement (0 months) may be your actual wait
- If you have lived in Montana for 0+ months already, you can file as soon as you are married
- The court may consider the stability of the family situation, but a recent marriage does not prevent filing
Our recommendation:
- If you meet the residency requirement and are married, file now
- Every month you wait is a month without legal parental rights
- The process takes 3-6 months from filing — start the clock today
