1. Long-term separation: If the husband and wife are separated for a long time and have no desire to live together, this may be regarded as effective evidence of emotional breakdown. It should be noted that the length and reasons of separation and the behavior of both parties during separation may affect the court's decision.
2. Domestic violence or abuse: If one party commits domestic violence or abuse to the other party, it is usually regarded as effective evidence of emotional breakdown. This may include physical violence or mental abuse.
3. Extramarital affairs: If one party has an extramarital affair, it is usually regarded as effective evidence of emotional breakdown. It should be noted that the evidence of extramarital affairs needs to be credible and conclusive, such as the testimony, photos or videos of a third party.
4. Economic problems: If the husband and wife have serious contradictions due to economic problems, they may also be regarded as effective evidence of emotional breakdown. For example, one party has serious gambling and debt problems.
5. Other evidence: In addition to the above circumstances, any evidence that can prove the breakdown of husband and wife's feelings can be accepted by the court. For example, the two sides do not have sex for a long time and do not fulfill their obligations as husband and wife.
It should be noted that the above are only some possible situations, and the specific evidence needs to be determined according to the specific circumstances of the case. In addition, when judging whether the relationship is broken, the court usually considers all the evidence, not just a single evidence. Therefore, if you encounter problems in divorce proceedings, you'd better seek professional legal help.
