Subject to change

Shen Xu, from Brighten Youth Up, a research institute in Shaanxi province for children's education and development, said some couples successfully divorce after 30 days. However, other applicants become anxious, being held back by partners who change their mind or even deliberately delay a divorce.

"Put simply, the cooling-off period is making divorce more open to doubt and subject to change," she said.

Shen used a couple she met after the policy was introduced as an example.

"We found that the woman had tried to ask her husband for extra money or to obtain a bigger percentage of mutual property in exchange for agreeing to divorce and allowing him custody of their child," Shen said.

Such additional requests during the cooling-off period increase the uncertainty of divorce, which might further affect the couple and their child, she added.

Chen Meigui, a social worker from Sanming, Fujian province, who conducts family-related surveys and mediates in domestic disputes, said she is also concerned about the policy, adding that questions relating to it need to be answered as soon as possible.

"First, it's vital to determine the exact relationship between the couple during this period," she said.

"Second, if one party finds that the other has borrowed a large sum of money during the 30 days, the action that can be taken needs to be clarified, along with whether the loan is a joint property."

Chen said there is a need to prevent people taking advantage of the cooling-off period to inflict additional worries on their partner.

"For instance, the conditions under which couples who apply for divorce can be granted an immediate separation should be listed promptly," she added.
