No, they vary by state and sometimes by county. We list average state‑wide filing fees; urban counties (Harris, Dallas, LA, NYC) may add surcharges.

Yes, in about 25 states (e.g., NY, NC, VA, TX) it's a factor; in no‑fault states like CA, it's generally not considered.
residency rules To file for divorce, at least one spouse must meet state residency (typically 6 months). If you move to a new state, that state's alimony laws will apply if you file after establishing residency. Example: moving from California (indefinite) to Texas (capped) can drastically reduce exposure — but must satisfy Texas residency (6 months). Courts also consider the "habitual residence" of the marriage.
📌 Always consult a family law attorney before relocating for divorce purposes. The Uniform Marriage and Divorce Act governs some jurisdiction issues.
