Parental financial favouritism can breed lasting resentment between siblings and occasionally escalate into legal battles over inheritance. Yet experts say families can take concrete steps to prevent these conflicts from taking root.
John, a 47-year-old whose name has been changed, experienced this tension firsthand. His parents declined to lend him £10,000 towards a house deposit following his separation, despite having the means to do so. Meanwhile, they had previously given his younger brother a down payment for a property purchase and covered portions of his living costs.
Growing up, John was positioned as the academically gifted child expected to achieve financial independence, while his brother, now 42, received what John describes as protective treatment as he struggled to establish himself. This pattern has left John convinced that "the needs of others take precedence over my own," contributing to feelings of isolation that have rippled through his friendships and romantic life.
According to research from Ameriprise, approximately 15% of siblings report conflicts centred on money matters, though notably 68% of these disputes actually concern parental finances rather than direct disagreements between siblings themselves.
Why money disputes run deeper than cash
Online communities including Mumsnet and Reddit overflow with accounts of siblings feeling shortchanged by unequal financial treatment. Complaints frequently centre on the volume of lifetime support parents provide to adult children, how wills distribute assets, and whether one sibling has shouldered more responsibility for aging parents.
Dr Fenia Christodoulidi, a counsellor at Relate, explains that these conflicts rarely concern money alone.
Financial support from parents often carries a powerful emotional meaning and some siblings tend to interpret differences in support as signs of favouritism, unequal love or a lack of recognition.
She notes that even when parents hold legitimate practical justifications for treating children differently—such as one child earning substantially less, facing health challenges, or needing extra funds to enter an expensive housing market—the failure to articulate these reasons clearly creates fertile ground for misinterpretation and hurt.
Do all families experience this tension?
Not every household struggles with money-related resentment. Ellis, 26, who works in finance in London, reports that she and her siblings have navigated "different levels of support at different times" without friction. Her colleague Tasha, the youngest of seven siblings, observes that her family members have occasionally clashed over perceived favouritism despite her belief that their parents treat everyone equitably.
I just think people sometimes get a bit uncertain or jealous and that's quite normal. Sometimes people stop talking for a bit or go to process what they are feeling, and they come back together and they just hash it out.Tasha, 33, suggests that temporary distance and reflection often allow siblings to reconcile.
How can families prevent these rifts?
Christodoulidi advocates for
open conversations about expectations and the reasons behind decisionsas a means of reducing resentment around financial matters. However, this approach proves impossible in households where discussing money remains taboo.
John describes his family as one where financial topics are off-limits.
Talking about money is verboten in my family - be it salaries or savings or financial assistance. Any time I've tried to air my feelings my parents just become evasive so now I don't bother.
He has resigned himself to planning his future without expecting an inheritance, though he anticipates being called upon should his parents require care or lose decision-making capacity. Despite maintaining a strong bond with his brother, John harbours resentment towards his parents for fostering this "imbalance."
What happens when disputes escalate?
Claire Webb, a solicitor and mediator at Family Solutions Now, regularly navigates inheritance and money conflicts between siblings. She describes a common scenario:
One sibling might argue the other was given more money earlier on in life, say, to buy a house, and that the parents said this would be reflected in the will. Then the will says, 'everything should be shared equally'. So you have all of that historic feeling of unfairness being dredged up.
To forestall such disputes, Webb emphasises that parents must communicate their intentions clearly while alive. When conflicts do materialise, inheritance disputes often hinge on legal claims such as undue influence, lack of capacity, or improper execution, rather than simply on a sense that a distribution feels unfair.
Webb recommends that siblings pursue mediation—where a trained professional helps resolve disagreements—before resorting to litigation. Encouragingly, siblings who do take legal action frequently reach amicable settlements.
Most of the time there is a deep-down family bond - and if you can crack what started the problem they often find a way through.
Practical steps to reduce family money conflicts
Experts and mediators suggest several approaches:
Recognise the emotional core: Disputes often reflect feelings about being valued or treated fairly rather than the monetary amounts themselves.
Avoid assumptions: Refrain from making judgments about a sibling's finances or the reasoning behind parental decisions without verification.
Create space for dialogue: Foster respectful conversations where each person can express their perspective without interruption or defensiveness.
Parents should communicate clearly: When supporting children unequally for practical reasons, parents must explain these rationales explicitly to prevent misunderstanding.
Seek professional help: Family counselling can assist when conversations repeatedly become stuck or emotionally charged.
Consider mediation early: A trained mediator can help siblings resolve disputes before they escalate to legal action.
Plan for incapacity thoughtfully: Parents typically designate their children as powers of attorney to manage care and finances if illness or cognitive decline occurs. However, when conflict risk exists, parents can appoint an independent third party, including a solicitor, instead.
