Writer Leo Tolstoy once observed that “All happy families are alike; each unhappy family is unhappy in its own way.” This may be true in the sense that families are complex units made up of complex individuals, and the ways in which they relate to each other and the circumstances in which they find themselves are unique. One family’s issues may be completely distinct from another’s.

Having said that, there are, nevertheless, a number of general patterns that frequently result in conflict within a large number of families, whether they are chosen or born. To compound the issue, many lack the tools to handle these challenges in a healthy way. Read on for eight of the most common sources of conflict in families, along with steps you can take to try and address or cope with them.
8 common causes of family conflict
If you’ve recognized that your family is experiencing conflict, identifying the root cause can be the next step toward managing it. Although many people are already aware of what’s causing the core conflict within their family, it can be helpful to see some of the most common ones listed out—both to provide insight into how multiple issues can overlap and interact, and to take comfort in knowing that you’re not alone in your experience of family problems. Some of the most common factors that lead to conflict or stress in families are listed below. Parental relationship problems
Parents who are constantly fighting—whether they’re still together or separated or divorced—can cause tension for all members, especially children. A parent who is having an unhealthy relationship with someone else can also be upsetting to watch. Financial concerns
Many families face serious challenges in meeting the basic needs of all members. Whether it’s because of systemic issues, job loss, inability to work, uncontrolled spending, gambling problems, or another reason, stress and conflict related to money and bills is common.

Health conditions
When one or more family members is experiencing a health challenge—from a chronic physical condition to a mental illness to a disability—it can affect the others. Stress and worry as well as providing care and paying medical bills can sometimes result in tension and other family issues.
Toxic behaviors between family members
Sometimes, stress or dysfunction in a family can be traced primarily to the toxic behaviors of one member. For example, someone who frequently engages in manipulation tactics, dishonesty, scapegoating, or similar behaviors can be extremely difficult or even dangerous to live with. These can be personality traits or signs of certain personality disorders.
Unaddressed trauma related to family issues
In most cases, trauma that has not been effectively and healthily recognized, processed, and healed will cause issues in a person’s life in some way. A family unit that experiences trauma together—such as war, a natural disaster, or the sudden death of a loved one—or vicariously through one member may experience conflict that arises as a result of this unaddressed pain. This can be especially true for various forms of intergenerational trauma.

Unhealthy expectations
Family members who feel pressure to conform to unhealthy and/or impossible standards may experience negative effects as a result. For example, a household where each child is expected to perform perfectly in school, never express negative emotions, or never bring up conflict can eventually cause them to disengage or lash out.
Too much or too little time together
Families that have to live in close quarters and spend most or all of their time together are liable to face conflict, as many learned during the COVID-19 lockdown. On the other hand, families that are so busy or live so far apart that they rarely get to spend quality time together could also end up experiencing conflict.
Poor or nonexistent communication
Healthy, honest, frequent communication is widely considered to be the foundation of healthy relationships of all types. Families without it are likely to experience recurrent conflict as issues that arise may not be properly addressed and members may not feel heard.
Addressing family conflict and promoting healthy relationships
After you’ve uncovered the root of the conflict your family is experiencing, the next recommended course of action is usually to engage in open communication about it with your family members. If you’re wondering how to resolve family conflict, setting aside a time when you can calmly and reasonably bring up the issue(s) without being aggressive or accusatory can be effective in some cases. Although you may not be able to solve all the issues with one conversation, it can represent a first step toward collaborating to create a happier, healthier family dynamic together over time.
However, sometimes it’s not feasible or not safe for one person to communicate something that’s been bothering them to others. Some family members may be resistant to even speaking openly about it, much less working toward solutions. It may be challenging to ever get to the bottom of the issue because of the extreme reactions that others may exhibit. In cases like these, therapy could be the next step to consider.
