Again, the key in these cases is to focus on relevance and concrete facts. No amount of repetition or pleading will convince a court unilaterally to take one side over the other. Instead, they will look to proven facts and strong evidence to support clear-cut reasoning.
If it is suspected that a spouse is making misleading statements in order to obtain more-favorable division of property or outcomes regarding children, facts will become the primary ally in the battle for truth. Spouses who feel suspicious of their former partner honesty should save all correspondence. They should keep a schedule of past events, a calendar dated and ideally reinforced with records of specific actions taken.
For example, a purchase of plane tickets made for a personal vacation that took place during an important birthday for a child can demonstrate a shallow relationship between the parent and the child. Similarly, evidence pointing to an unwillingness to advance income-earning potential on the part of a spouse, despite ample time, resources, and justification, can indicate a desire to extract as much value as possible from a marriage.
While neither hypothetical example is airtight, they demonstrate how general assertions must be documented and assembled into a compelling narrative, with legal justification to back it up, if someone wishes to have a higher chance of success in a contested divorce hearing.
