After information is input into a computer, the software will provide a range for the spousal support amount and duration. Although there is no set formula to determine the exact amount and duration of spousal support, there are guidelines, referred to as the "Spousal Support Advisory Guidelines", which provides ranges for both. "The Spousal Support Advisory Guidelines" calculates the ranges taking into account the factors set out above. Although the courts are not required to abide by the "Spousal Support Advisory Guidelines", they are required to take them into account when deciding on the issue of spousal support. Depending on the means and needs of the individual receiving support, the court will generally award an amount of spousal support somewhere within the range provided by the software. The longer the relationship, the greater the presumption that the parties should have an equal standard of living. Similarly, the length of the relationship will be taken into account when determining how long spousal support should be paid for. Awards for spousal support can be for a limited term or indefinite. While declaring bankruptcy does not absolve Canadians of obligations to pay alimony or child support, a 2011 ruling by the Supreme Court of Canada established that under current laws "equalization payments agreed to as part of a divorce are considered debts, and are wiped off a person's balance sheet when they declare bankruptcy." Laws of the Czech Republic provide for spousal maintanance both during marriage and after divorce. As main principle, both spouses have the right for generally equal standard of living during the marriage. The same "generally equal standard of living" applies also to post-divorce period in special cases, when the payee wasn't mostly responsible for the failure of marriage or did not agree with the divorce and the payee suffered serious harm due to the divorce and hadn't committed an act of domestic violence against the payer. In such case the payee may request alimony in amount providing "generally equal standard of living" for a period adequate to circumstances, but no longer than three years. If those special conditions are not met, both of the divorced have mutual spousal maintanance obligation in case that one of them is not able to provide for themselves due to circumstances originating in marriage, if payment of alimony is reasonable under general circumstances that each of the divorced found themselves in.
