of their own free will without having to prove someone is at fault for the divorce. Many jurisdictions offer both the option of a no fault divorce as well as an at fault divorce. This is the case, for example, in many states of the US, France and the Czech Republic. Though divorce laws vary between jurisdictions, there are two basic approaches to divorce: fault based and no-fault based. However, even in some jurisdictions that do not require a party to claim fault of their partner, a court may still take into account the behavior of the parties when dividing property, debts, evaluating custody, shared care arrangements and support. In some jurisdictions, one spouse may be forced to pay the attorney's fees of another spouse. Laws vary as to the waiting period before a divorce is effective. Also, residency requirements vary. However, issues of division of property are typically determined by the law of the jurisdiction in which the property is located. In Europe, divorce laws differ from country to country, reflecting differing legal and cultural traditions. In some countries, particularly (but not only) in some former communist countries, divorce can be obtained only on one single general ground of "irretrievable breakdown of the marriage" (or a similar formulation). Yet, what constitutes such a "breakdown" of the marriage is interpreted very differently from jurisdiction to jurisdiction, ranging from very liberal interpretations (e.g. Netherlands) to quite restrictive ones (e.g., in Poland, there must be an "irretrievable and complete disintegration of matrimonial life", but there are many restrictions to granting a divorce). Separation constitutes a ground of divorce in some European countries (in Germany, e.g., a divorce is granted on the basis of a 1-year separation if both spouses consent, or 3-year separation if only one spouse consents). Note that "separation" does not necessarily mean separate residences – in some jurisdictions, living in the same household but leading a separate life (e.g., eating, sleeping, socializing, etc. separately) is sufficient to constitute de facto separation; this is explicitly stated, e.g., in the family laws of Latvia or the Czech Republic. Divorce laws are not static; they often change reflecting evolving social norms of societies. In the 21st century, many European countries have made changes to their divorce laws, in particular by reducing the length of the necessary periods of separation, e.g., Scotland in 2006 (1 or 2 years from the previous 2 or
