on a simple allegation of 'irreconcilable differences,' 'irretrievable break-down', or 'incompatibility' with respect to the marriage relationship, or on the ground of separation. Summary divorce A summary or simpledivorce, available in some jurisdictions, is used when spouses meet certain eligibility requirements or can agree on key issues beforehand. Key factors: Short duration of marriage (less than five years) Absence of children (or, in some jurisdictions, prior allocation of child custody and of child-support direction and amount) Absence or minimal value of real property at issue and any associated encumbrances such as mortgages Absence of agreed-as-marital property above a given value threshold (around $35,000 not including vehicles) Absence, with respect to each spouse, of claims to personal property above a given value threshold, typically the same as that for total marital property, with such claims including claims to exclusive previous ownership of property described by the other spouse as marital No-fault divorce Most Western jurisdictions have a no-fault divorce system, which requires no allegation or proof of fault of either party.
