IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION THREE

In re the Marriage of REBECCA MUMMA 

and DON ROSENFIELD.

REBECCA MUMMA,

Appellant,

v.

DON ROSENFIELD,

Appellant.

A134292

(San Francisco County

 Super. Ct. No. FDI-04-757877)

Rebecca Mumma appeals from a November 22, 2011, order denying her request 

for a downward modification of spousal support in favor of Don Rosenfield. She asserts 

the court erred as a matter of law by refusing to consider her loss of tax deductions after 

the sale of the marital residence as a factor impacting her ability to pay spousal support. 

We agree with Mumma, and accordingly, we shall reverse and remand the matter for 

further proceedings.1

FACTUAL AND PROCEDURAL BACKGROUND2

Mumma and Rosenfield were married on November 29, 1990 and separated in 

October 2004. On September 19, 2006, the parties entered into a stipulated judgment of 

 

1

In light of our determination, we dismiss as moot Don Rosenfield‟s cross-appeal 

from so much of the November 22, 2011, order as denied his request for attorney fees.

appeal.

dissolution that incorporated a marital settlement agreement (the “MSA”), outlining each 

party‟s respective property interests and support obligations. The MSA required Mumma 

to pay support to Rosenfield in the base sum of $2,350 per month. The monthly sum was 

modifiable under the following circumstances: “The parties agree [Mumma] may seek a 

downward modification of spousal support upon a showing of changed circumstances. 

However, under no circumstances shall any court have jurisdiction to modify spousal 

support upward or in any way increase the amount of spousal support payable by 

[Mumma] to [Rosenfield]. The parties agree that the sale or transfer of the former family 

residence. . . shall constitute a change of circumstances sufficient for [Mumma] to request 

a downward modification of support.” 

On May 14, 2010, Mumma filed a motion for downward modification of spousal 

support based on her change in income, which was opposed by Rosenfield. In support of 

her motion, Mumma informed the court the marital residence was “in escrow and 

scheduled to close escrow shortly.” The house sale closed on June 1, 2010. 

A superior court commissioner assigned to the case held a hearing on August 26, 

2010, and later presided at a judicial settlement conference on October 7, 2010, after 

which the parties stipulated that a decision would be rendered on all issues presented by 

the parties‟ pleadings. In the commissioner‟s written order filed on November 30, 2010, 

Mumma‟s request for a downward modification of spousal support retroactive to May 

2010 was denied because she had failed to demonstrate that a substantial change of 

circumstances beyond her control had caused a decrease in her ability to pay the current 

support order. In so ruling, the commissioner commented that Mumma had not provided 

sufficient documentation regarding her current pay and benefits, and her income and 

expense declaration “was stale, given the new status of the sale of the house and the old 

mortgage figures no longer apply.” 

On December 15, 2010, Mumma filed a motion for reconsideration, which was 

opposed by Rosenfield. The commissioner denied the motion for reconsideration, but 

ruled that Mumma could file a new motion. However, the commissioner advised 

Mumma that she would be required to meet the legal standard for a downward
3

modification based on changed circumstances, and Rosenfield would have an opportunity 

to inquire into and cross-examine Mumma on the matter. 

On January 27, 2011, Mumma filed a new motion for downward modification of 

spousal support. In support of the request, Mumma asked the court to consider numerous 

changed circumstances, including that since the last order, her work as an independent 

contractor had ended, she was now a salaried employee on a fixed income, she was no 

longer able to generate additional income without explicit approval of her employer, and 

in 2011, she would pay higher taxes and no longer be able to claim income tax 

deductions for property tax and mortgage interest because of the sale of the house. In a 

supplemental declaration filed on June 27, 2011, Mumma again contended she was filing 

the motion based on numerous changed circumstances, including her change in 

employment and income, and that “[t]he judgment specifically states that the sale of the 

residence would constitute a change of circumstances. The residence sold between the 

time she filed in May 2010 and the present. [She] no longer has the tax benefits from 

home ownership. . . .” 

On November 22, 2011, Mumma‟s motion for downward modification of spousal 

support was heard before a superior court judge. After argument, the court denied 

Mumma‟s motion in a written order, finding as follows: “1. There exist no changed 

circumstances from the time of the prior hearing on a motion for modification on 

August 26 to the current hearing on motion for modification that would justify revisiting 

the issue of spousal support. 2. The sale of the home was not raised by the parties, 

argued to the Court in pleadings, or appears to have been considered by [the court 

commissioner] in her order of November 30, 2010. 3. [The commissioner‟s] calculations 

incorrectly applied the mortgage payments and property tax payments as the house had 

been sold prior to the August 26 hearing and her November 30, 2010 order. 4. The house 

had been sold at the time of the litigation and the order and no appeal was made to [the 

commissioner‟s] November 30 ruling. 5. The Court has no jurisdiction to reconsider 

issues that were already in existence when [the commissioner‟s] order was made 

following the August 26, 2010 hearing.”

DISCUSSION

We agree with Mumma that the November 22, 2011 order must be reversed 

because the court should have considered the impact of the loss of tax deductions after 

the house sale as a factor in determining her ability to pay spousal support. At the time 

Mumma‟s original motion was filed in May 2010, the house had not been sold, and she 

did not amend her motion papers after the sale. The commissioner‟s November 30, 2010 

order resolved only those issues raised in Mumma‟s motion papers, and did not consider 

or rule on the impact of the loss of tax deductions after the house sale as a factor in 

determining her ability to pay spousal support. Consequently, there was no bar to 

Mumma‟s later request for a downward modification of spousal support and the court 

erred in finding that it lacked jurisdiction to consider the matter. As explained by the 

court in Allied Fire Protection v. Diede Construction, Inc. (2005) 127 Cal.App.4th 150, 

“ „The scope of litigation is framed by the [pleading] at the time it is [first] filed.‟ 

[Citation.] [¶] Res judicata is not a bar to claims that arise after the initial [pleading] is 

filed. . . . The general rule that a judgment is conclusive as to matters that could have 

been litigated „does not apply to new rights acquired pending the action which might 

have been, but which were not, required to be litigated [citations].‟ ” (Id. at p. 155.) 

While it may have been more efficient if Mumma asked the court to consider the impact 

of the loss of tax deductions after the house had been sold, under res judicata principles, 

she was not required to do so as part of her May 2010 motion. (Ibid. [no requirement to 

amend a pleading to add newly acquired claims]; see Brown v. Brown (1915) 170 Cal. 1, 

6; Kettelle v. Kettelle (1930) 110 Cal. App. 310, 312.) 

However, we deny Mumma‟s request that the matter be remanded to the court for 

the limited purpose of a calculation of the dollar amount by which her spousal support 

obligation should be reduced. We cannot conclude, as a matter of law, that Mumma‟s 

loss of tax deductions as a consequence of the house sale, standing alone, is sufficient to 

require a downward modification of spousal support. Accordingly, on remand, the court 

is directed to determine whether Mumma is entitled to a downward modification of 
5

spousal support based on all relevant factors. Our decision should not be read and we 

express no opinion on how the court should exercise its discretion in deciding the matter.

DISPOSITION

The November 22, 2011, order is reversed and the matter is remanded to the 

superior court for further proceedings consistent with this opinion. Don Rosenfield‟s 

cross-appeal is dismissed as moot. Each party shall bear their own costs on appeal.
