California Child Support Custody Impact Tables
A 30-volume set that highlights financial calculations in child support depending on a party’s custody percentage and their monthly net disposable income. Each volume highlights a range of income in addition to a number of children from one to ten. The California Child Support Custody Impact Tables, part of the Litigation Support Series by Jeremy J. Salvador, is a reference tool designed for family law attorneys, judges, and mediators to verify calculations, anticipate outcomes, and clearly explain child support guideline results in relation to the party’s custody percentages.
Every Percentage Point Has a Price
The guideline formula does not treat custodial time as a footnote to income. The approximate percentage of time factor sits inside the same equation as the parents’ earnings, and moving a schedule from a 20% to a 30% timeshare can shift a support order by a meaningful amount every month.
This release covers fifteen income brackets, from $0 to $314,000 in monthly net disposable income, for households of both one to five and six to ten children. Each volume covers the full range of custodial timeshare within its bracket, so users are prepared for any scenario.
Thirty Volumes. One Set
Every two volumes cover the same income bracket, one covering one to five children with the other covering six to ten children.
A Reference with Quality
Family Law cases require precision, not estimates. These volumes exist so the custodial-time side of that formula gets the same rigor as the income side.
Comprehensive Coverage
Timeshare calculations from 0% - 95% every volume across a range of incomes.
Expert Authorship
Written by a testifying forensic accounting expert, not a general reference publisher.
Professional Grade
Built for courtroom and mediation use, not casual estimation.
Statutory Precision
Every table traces back to Family Code §4055’s timeshare factor.
Every Timeshare Percentage Changes the Number
We help parents and all other professionals associated with child law understand how custodial timeshare moves a guideline support number, with clarity and confidence. Custody disputes bring enough uncertainty. These books make sure the financial side of a parenting schedule doesn’t add to it. By breaking down the timeshare factor of section §4055 of California’s Family Code, these books are reliable sources for parents, attorneys, mediators, and more.
Our Mission
Helping parents and professionals understand how custodial timeshare affects support obligations, with clear guidance under §4055.
Our Vision
A family law process where a shift in a parenting plan is never a financial surprise for either parent.
Values
We put children first, provide clear and accurate calculations, act with fairness, and build trust through transparent math.
Understanding Built on Experience & Care
We know how much weight a parenting schedule carries in a negotiation, and how easy it is for the financial side of it to stay unspoken until it becomes a dispute. Our approach combines statutory precision with plain language, grounded in the same §4055 timeshare factor courts already apply, so parents, attorneys, and mediators alike find guidance that is both technically sound and genuinely useful.

Reads Alongside the Guideline Series
These volumes are not a substitute for the California Child Support Guideline Calculations series, they extend it. Both are organized the same way, by income bracket and children count. Where a Guideline volume gives the support number for a standard timeshare assumption, the matching Custody Impact volume shows how that number moves as custodial timeshare changes within the same bracket.
How to Use Both Series Together
Start with the Guideline volume for your income bracket and children count. Then open the matching Custody Impact volume to see how the number shifts across the timeshare arrangement you are negotiating or litigating.
